Abstract (en)
The present disclosure discloses a method and apparatus for extracting a video clip, relates to the field of artificial intelligence technology such as video processing, audio processing, and cloud computing. The method comprises: acquiring (201) a video, and extracting an audio stream in the video; determining (202) a confidence that audio data in each preset period in the audio stream comprises a preset feature; and extracting (203) a target video clip corresponding to a location of a target audio clip in the video; wherein the target audio clip is an audio clip within a continuous preset period, and has a confidence that the audio data comprises the preset feature, which is larger than a preset confidence threshold. This method may improve the accuracy of extracting a video clip.
